Sounds like missing on rear rotor then....check for nice strong puffs on rear rotor.....heat light on strange? Torch onto dash lights will show you warning lamps presents.
Id take off the tb and worry about gaskets later tbh. Nice to get them magnecor leads on with the new sparks and you can check over them coils. Good luck.

There's nice strong even sounding puffs when cranking without plugs.

Will check lamps tomorrow.

Will give the leads a go tomorrow.

Just had the throttle body off and checked spark again.

The two leading coil packs are only giving a faint yellow spark so that probably explains why the engine isnt starting!

Could it just be a coincidence that both of those are not working as they are seperate to the trailing, and it be the ignition amp that has gone?

Has anyone near Swanley, got some coilpacks and ignition amp i can borrow for testing?

Are there any uprated coilpacks and ignition amp I can buy?

Reading that id be checking you got a full 12V supply to the coils as the ignitor is doing its job. leading or trailing poor spark?

Thanks for that link mate.

Its both the leading coilpacks that are giving crap spark, the trailing run off the same one and that seems fine.

Actually think i might have got that the wrong way round!

The single leads packs are the ones that are crap anyway!

That confused me as well i thought the trailing was wasted spark. Good write up and can check the 12 v and ground on that ignitor. ebay has an ignitor for 40 pounds and coil packs as well.

This could be a longshot, but check wirings fron trickerwheel (crank angle sensor, or something like that)

I think its getting wrong signal from some reason...
Power is nothing without control. Weight is enemy of performance, handling and braking.
